UNITED STATES PATENT OFFICE.

WILLARD I. LEWIS, OIE WALPOLE, MASSACHUSETTS, ASSIGNOR TO WILLIAM F. MAREESFORD, OF BROOKLYN, NEW YORK.

MACHINE FOR. APPLYING FLY-LEAVES AND THE LIKE TO THE SIGNATURES OF BOOKS.

Application filed June 30, 1906.

To all whom "it may concern:

Be it known that I, WILLARD I. LEWIS, a citizen of the United States, residing at Walpole, in the county of Norfolk, State of Massachusetts, have invented a certain new and useful Improvement in Machines for Applying Fly-Leaves and the like to the Signatures of Books, of which the following is a specification, reference being had therein to the accompanying drawings.

In the art of book-binding, one of the operations preliminary to assembling and se curing together the signatures, etc., constituting the body of a book, is to attach, with the aid of cementitious material such as glue or paste, certain additional sheets to certain of the said signatures. In some instances a single or unfolded sheet, constituting a flyleaf, is united along one margin thereof to one face of an end-signature, adjacent the inner or folded edge of the said signature, such a fly-leaf being attached to each endsignature. Cuts and the like are united in like manner to the appropriate signatures. In other instances, a sheet which is folded upon itself at its middle is attached or united adjacent the fold thereof to the exterior of an end-signature. Such a folded sheet is variously termed a fly-sheet or an end-paper. In subsequently completing the binding operations, onehalf of the said fly-sheet or end-paper is pasted to the inner surface of the adjacent side of the cover, to constitute a lining therefor, while the other half constitutes one of the fly-leaves of the book. In the case of the first signature of a book, the fiy-leaf, or fly-sheet or end-paper, is applied to the front of such signature; in the case of the last signature of a book, the fiy-leaf, or fiy-sheet or end-paper, is applied to the back of the same. A cut or the like sometimes is attached to the front of a signature, and sometimes to the back of a signature.

My invention has for its general object to provide an automatic machine of novel character by means of which single fly-leaves, folded or doubled fly-sheets or end-papers, and cuts, as well as other like parts of books, all of which for convenience of designation will be comprehended generically under the term fly-leaves in the following description, may be attached to signatures of books or the like.

One object in particular of the invention is to provide an automatic machine by means Specification of Letters Patent.

Patented Feb. 2, 1915.

Serial No. 324,236.

of which fiy-leaves or cuts may be attached to the backs or the fronts of.signatures according as may be desired. the machine being serviceable, both for the attachment of fiy-leaves and cuts to the fronts of those signatures with which such attachment is necessary, and for the attachment of fly-leaves and cuts to the backs of those with which the latter attachment is required.

A further object in particular is to provide a machine in which the work of attaching fly-leaves or cuts to the fronts of one set of signatures may be performed simultaneously with that of attaching flv-leaves or cuts to the backs of a second set of signatures.

A further object in particular is to provide a machine in which the fly-leaves or the like, either single or folded, are formed from a continuous strip or web of paper by doubling. when required, the said strip longitudinally upon itself, then cutting the same into lengths suitable for flv-leaves, and automatically feeding the said lengths and the signatures with which they are to be connected to the devices by which the respective fly-leaves and signatures are'assembled and united.

I have herein illustrated my invention as embodied in two forms of machines which are constructed and organized to attain the first two particular objects just mentioned, although in some instances the broader fea tures of the invention, as defined hereinafter, may be embodied in a machine in which the third of the said objects is not sought to be attained. The main principles of my invention may be carried into effect by various forms. constructions, and arrangements of the different devices.

Having reference to the" drawings, the base of the framing is designated 1 in the case of each of the machines that are shown.

From the said base rise stands "or uprights supporting the various working and other .parts to which reference will be made. The

driving shaft in the case of each machine is "shown at A, it being'journaled in bearings with which the stands A A are furnished.

2 1a band -pulleyA to recei e a 'su'i'tabledriving band- (not shown), is fast upon shaft A.

Referring to the form of machine shown in Figs. 1 to 10, the stands or uprights which are designated 2, 2, in Figs. 1, 3 and 6, supfrom the vsaid is a plan I the supporting port horizontal tables 3, 3, extending parallel with each other lengthwise of the ma"- chine., The said tables are located at opposite sides of the machine. Each of the said tables 3 is formed at its upper side with longitudinally-extending parallel grooves 31, 31, as shown best in Figs. 3, 4 and 5. Upon the upper surface of each table are secured thin metal strips 32, 32,the proximate edges of which, as shown best in Figs. 3, 4 and 5, project partly across the grooves 31, 31, but are, separated by spaces constituting narrow slots extending. lengthwise of the table. The strips 32, 32, form in combination a supporting guide-way for the-fiy-leaves which are operated upon in the. machine. The said flyleaves are laid in succession upon the said strips at the receiving end of the machine, such end being at the right hand side in Fig. 1, and are fed in sequence along; the same.- Above' the series of strips 32, 32, in connection with each table3, is arranged, a second series of strips 33 33, in close proximity to the strips32,32. The said strips 33, 33, are shorter than the strips 32, 32,'and respectively correspond in position vertically with the respectivestrips 32, the supply-end of the machine the strips 33, 33, corresponding with each table 3 pass beneath= a transverse bar 34, Fig. 7, the latter hating its ends fastened by screws tothe top portions of blocks 35, 35, thelatter rising table 3 at the inner and outer of the two'series of strips 33, 33, are-bent upsides, respectively, 32 and 33.1 The strips wardi around the bar 34, and their ends are fastened "by-screws to the topside of the the bars 34, 34, inorder to afford opportu ni ty to lay the flyleavesupon the said strips 32, 32, in advance-of the-said bars 34, 3'.

The signatures which are to' have the flyleavesconnected therewith are placed upon the strips 33,33, adjacent thebar 34, and in the operation of the .machine are moved along the same ,towardthe delivering'end of the machine, in unison with the fly-leaves below the same restingxupon' the strips 32, 32. For 'the'purpose' of feeding the fly leaves and signatures automatically along guide-ways therefor, feedchains 4, 4, are'employed. At the opposite endsof the machine the saidfeed-ch'ains pass around sprocket-wheels 41, 41, and 42, 42. At the supply-end of the-machine the sprocket-wheels are mounted. upon asupporting shaft 41 extending transversely acrossthemachme and ournaled in bearings upon standsor uprights 211,: 21,; Figs. 1

and 2. The sprocket-wheels 42, 42, at the delivering-end of the machine are fast upon a transverse shaft 43 which is journaled in bearings upon the upright stands 22, 22,

Figs. 1 and 6. For the purpose of actuating the feed-chains, intermittent rotary movement is communicated to the shaft 43 in a manner which is explained later herein. The upper length of each feed-chain intermediate the corresponding sprocket-wheels 41, .42, works Within the runway constituted by one of the grooves 31 of a table 3, the feed-chain resting and sliding upon the bottom of said groove. See Figs. 3, 4 and 5. For engagement with the fly-leaves and signatures, to cause them to travel in unison with the feed-chain, the links of the latter are furnished with pins 44, 44, projecting therefrom, and which in the travel of the chain through the grooves 31, 31, extend upward through the slots between the strips 32, 32, and 33, 33. The pins are of sufficient length or height to rise somewhat above the upper surfaces of the strips 33, 33.

In operation, a fly-leaf laid upon the strips 32, 32, of either table 3 at the supplyend of the machine, will be engaged in the advance of the feed-chains by the next suc ceeding pins 44, 44. By the movement of the feed-chains, the said fly-leaf will be carried along the slideway constituted by the strips 32, 32. As the feed-chains move along, a signature placed upon the strips 33, 33, in advance of the cross-bar 34, will be engaged by the said pins and thereafter such signature and the said fly-leaf will move along in company, the one thereof vertically above the other and the rear ends of both thereof registering with each other in consequence of the mutual engagement of such ends with the same pins 44, 44. As applied to the strips 32, 33, the fly-leaves and signatures are laid thereon with the headends thereof, that is to say, the ends thereof which are at the top in a book, turned toward the front end or supply-end of the machine. Hence, by the engagement of the pins 44 with the head-ends of the fly-leaf and signature, the said head-ends are caused to register with each other as the pins push the fly-leaf and signature along the resnective supporting guide-ways.

In placing the fly-leaf upon the strips 32, 32, of either table, one edge of the flyleaf is placed in contact with an edge guide 5 Figs. 2, 3 and 7 rising above the level of the upper surfaces of the strips 32, 32, and thereby the position of the fly-leaf laterally as it journeys forward through the machine is determined. In case of a folded fly-leaf or end-paper the folded edge thereof is placed in contact with the edge-guide 5. When the signature is laid upon the strips 33 constituting the way therefor, it is applied thereto with its folded edge projecting slightly beyond the line of the edge-guide 5, in order that the marginal portion of the signature adjacent the line of the fold may extend beyond the corresponding edge of the fly-leaf, in position to be acted upon at the under surface thereof by the paster as the signature and corresponding fly-leaf move forward together. For the purpose of correctly positioning the signature laterally in connection with each table, so as to insure a proper extent of projection beyond the edge of the fly-leaf, I provide the back-edge gage 6. Preferably, each of the said backedge gages is movable in a direction at right angles to the length of the slide-ways for the signature and fly-leaf, and is provided with means for reciprocating the same in such direction, that is to say, transversely with relation to the slide-ways, in order that by its inward movement it may by contact with the folded back-edge of the signature push the latter transversely across the slide- Way 33, 33, into exactly the proper position. In this instance, the edge-gage 6 at each side of the machine is attached to and supported by an arm 61, see more particularly Figs. 4 and 9, of a'rocker which is pivotally mounted in a stand 62 upon the base 1, the said rocker having an arm 63 extended toward the middle of the machine, where it is in operative engagement with a cam 64 on the main or driving shaft A. Through the action of the cam 64 the back-edge gages 6, 6, at the opposite sides of the machine are moved to engage with the signatures and shift or jog the same transversely upon their slide-ways. The return movements of the back-edge gages 6, 6, are produced by the action of suitable springs, not shown.

After the signature has been positioned in readiness for the application of glue or paste to the margin thereof adjacent its back-edge, the movement of the feed-chains causes the projecting marginal portion of the signature to make contact with the glue-applying or pasting-device and travel past the latter. In the present instance, the pasting device at each side of the machine consists of a roll 7 partly immersed in a paste-trough 71, the paste-roll 7 having in conjunction therewith a presser-roll 72 by the action of which the under surface of the projecting marginal portion of the signature is held firmly in contact with the paste-covered surface of the roll 7 as the signature travels past the latter.

In order that the presser-roll 72 may not become covered with paste through contact with the surface of the roll 7 at the times when no signature separates the two rolls from each other. the presser-roll is mounted with capacity for movement toward and from the paste-roll and has combined therewith means for separating the same from the paste-roll as a signature passes from between them. and allowing it to move toward the paste-roll again as the leading end of the next signature arrives in position to make contact with the paste-roll. In this instance, the presser-roll 72 .in connection with each paster ismounted upon a movable carrier which is constituted by a bell-crank 73, the latter being pivoted at 74 to one edge of-fthetable 3. The said. carrier 73 is acted upon by the tension ofa contracting spiral spring 75 having one extremitythereof connected with the upright 2 adjacent theYde livery end of the machine, the said spring operating with a tendency to move the earrier. 7.3, in the direction'to carry the presserroll .72.,toward. the paste-roll 7. 'fForjthe purposeof operating the carrier to separate the .presser-roll from thepaste-roll, a cam 7.6 is providedupon the shaft 43, thel'said cam acting against a. roll 7 6? which is'pivotally mounted upon a yoke formingpart of a rod.77 that is jointedat one emi thereof to thecarrier 73, The yoke is slotted, and fits and slides upon the shaft 43, as shown in Fig. 1. The spring 75 acts to hold the roll 76 in contact with the periphery of the cam. a j

,After the signaturehas had glue" or paste applied to the projecting marginal portion thereof. by means of the glue or paste-applying device, and has passed beyond the latter,

- the said marginal portion ,of the signature is caused to register with the corresponding marginal portion ofthe fly-leaf in order to place the signature; and fly-leaf inreadiness for being united to each other. To this end the foldedback-edge of the signature is engaged by a back-edgev registering device which operates to shift or jog the signature transversely to the extent necessary to cause the signature and flyleaf to register as aforesaid. A. device for the purpose is shown at 8 in connection with each table '3. The-devices S, 8, are mounted to reciprocate transversely with relation to the slide ways,

and to this end each thereof is attached to the upperend of an arm 81of a rocker that is mounted pivotallyupon a stand 82 supported by the base 1, the said rockerhaving in connection therewith asecond arm 83 in into register with each tion of the back-edge registering device 8,

l chine a pair of compressing-jaws The'said aws are carried, respectively,

vthe back-edge reg stering operative engagement with a cam '84 upon the main shaft A. The cam acts to move devices 8, 8, inward to engage the signatures, the outward movement of the said devices being proi duced by the action of a spring or springs, not shown. I j K v After the back-edges of a signature and the corresponding fly-leaf havebeen brought other through the acthe signature and fly-leaf are pressedtogether to-insure the union thereof. For this purpose I employ at each side of the nia- 9. and 10.

arms 91, 10 of rockers which are mounted pivotally upon a short shaft 11, Fig. '5, which is supported by stands 12, 12, rising from'the base 1. The arm 91 at one side of themachine and the arm 10 at the opposite side of the'machine constitute parts of the same rocker. For the purpose of communicating movement to the rockers so as to move them simultaneously'but in opposite directions with relation to each other, the said rockers are furnishedwith downward extensions which are both connected by means of links 13, 13, Figs. 1 and 5, to the pivot 13" on the inner arm or end of a radius-arm 14, Fig. 5, the latter being pivoted at 14"**up0n a stand 14 risingfrom the base 1, and the said pivot working in the groove of a cam disk 15 upon the shaft A. In order to render the action of'the jaws 9 and 10 of the pressers yielding, each of the same is formed as a separate piece having slots therethrough, as at 92, are passed the stems of screws 93,93, the heads of the said screws serving to hold the said jaws to the outer extremities of the respective arms of the rockers. The slots permit -movement of the jaws upon the said arms in the direction ofthe said slots. The jaws are backed up by compression-springs 94, 94, Fig. 5, which are partly contained in pockets with which the jaws are formed, the said springs acting by their outer ends against flanges 95, 95, projecting from the arms of the rockers. The springs serve to hold the jaws up to their work, but should an unusual thickness of material intervene between the acting faces of a pair of jaws, the springs will yield to avoid breakage or injury. I I

After the separation of the jaws 9, 10, from each other, the-movement of the feedchains takes the united signature and flyleaf from between the jaws, and discharges them from the rear ends of the strips 33, To'perinit of this discharge, the said ends of the strips 33, 33, are connected with the cross-bar 33 Figs. 1, 2, 6 and 10. The said cross-bar is attached at intermediate points in its length to the upper ends of the stands '22, 22, its ends'being free so that the con- 'nected'signature and fly-leaf at either side of the machine may pass above and below thesame See more particularly Fig. 10. p

The step-by-step movement of the feedchainsis produced by imparting intermittent rotary movement to the shaft 43. This is effected by means of an intermittent clutch-device and operating connections between the same and the main shaft A. See Fig. 8. The said intermittentclutch-device comprises in the present instance a single toothed wheel 43 Figs. 2, 6 and 8 that is fast upon the shaft 43, and a pawl 43 that is adapted to engage with the tooth of the said wheel'and is mounted 'pivotally upon an arm 43 which is sleeved upon the shaft 431* The operating connections between the intermittent clutch-device and the shaft A comprise a spur-gear 4:? which is fast with the arm 43, and a rack 13 which is held in engagement with the spur-gear 13 by means of a guide d3, the said rack having a crosshead 43 in which works a block which is connected with a crank 43* upon the shaftA.

Usually, in practice, .the back-edge registering devices are given a sufficient extent of movement inward to cause them to engage with the back-edge of the fly-leaf as Well as that of the signature, so that after such edge of the signature has been engaged and the latter moved transversely upon the upper strips or guideway, the flyleaf shall be engaged also by the back-edge registering device and moved thereby a short distance in unison with the signature. Thereby I guard against the possibility of defective joining of a signature and fly-leaf inward from the outer edge of the lower strips or guideway.

The two sets of pasting devices and backedge registering devices are reversely-related with respect to the head-end registering devices which are constituted by the feed-chains and the projections thereof which engage with the head-ends of the flyleaf and signature. In the present instance, the pasting and back-edge registering de vices at one side of the machine are located at the left-hand side of the said feedingchains, while those at the other side of the machine are located at the right-hand side of the feeding-chains. The consequence of this is that when a signature is laid upon the upper guideway with its back-edge in position at one side of the machine to enable the adjoining marginal portion of the downturned face of the signature to be acted upon by the pasting devices at such side, the paste will be applied and the fiy-leaf will be at tached to one face of the signature, while when a signature is laid with its back-edge in position at the other side of the machine to enable the adjoining marginal portion of the face of the signature which is there turned down, the paste will be applied and the iv-leaf will be attached to the other face of the signature. Thus, in the drawings the devices at the left hand side of the machine will act to attach the fly-leaf to the front of the signature, while those at the right-hand side thereof will act to attach the fly-leaf to the back of the signature.

The machine comprises, essentially, right and left mechanisms which are adapted to attach fiy-leaves and the like in reverse relaticns to signatures. The said machine consists, in effect, of duplicate attaching or combining devices, and oppositely-disposed gaging or back-edge registering devices whereby to permit the fly-leaves to be attached in the said reverse relations to the signatures. It has been devised with more especial reference to providing a twin machine for enabling one series of signatures to have fly-leaves attached to the front thereof, and at the same time a second series to have fly-leaves attached to the backs thereof, but it will be obvious that if it is not .desired to operate upon two series of signatures simultaneously then either set of the pasting and back-edge registering devices alone may be utilized, according as it is desired to apply fly-leaves to the fronts of signatures or to the backs thereof. While I have shown two tables, with corresponding sets of guideways for the flyleaves and signatures, it will be obvious that the extent of the separation of the same is not material, and also that it is not essential to the invention in all its phases that separate tables and guideways should be employed.

In the machine shown in Figs. 11, 12, 13, etc., a continuous strip or web of paper is severed into lengths, suitable for fly-leaves or endpapers, which are delivered successively to the guideway for fly-leaves or end-papers in position to be engaged by the feedchains. Signatures contained in a hopper are fed automatically from the latter to the guideway for signatures, in position corresponding with that of the fiy-leaf or end-paper which is to be united thereto. The machine is adapted to be employed in attaching single-sheet fly-leaves, cuts, or the like, but for the purpose of attaching doubled fly-sheets or end-papers I provide the same with a device for doubling the web of paper upon itself longitudinally. The registering, paste-applying, and pressing devices resemble those of the machine which already has been described. After passing the pressing devices the connected signature and fly-leaf or end-paper are pushed off the rezlir ends of the guideways upon a delivery be t.

In the machine shown in Figs. 11, 12, 13, etc., a band-pulley A is fixed on a driving shaft A, which is mounted in hearings in a stand A attached to base 1, the said driving-shaft being furnished with a spurpinion A meshing with a spur-gear A that is fast on shaft A.

16, 16, are turn-tables located at the opposite sides of the machine, at the front or feeding end of thelatter, and designed for the support of the rolls of paper from which the fiy-leaves or end-papers are to be formed. Each turn-table is furnished with an upwardly-extending spindle, 16 to enter the central opening of the roll of paper which is applied to such turn-table, and is furnished, also, with a downwardlv-extending shaft, 16 fitting within a supporting sccket, 16, on the machine-frame, within which socket the shaft is adapted to turn. For the purpose of effecting vertical adjustment of the turn-table and the roll of paper mounted thereon, an'adjusting screw, 16*, is applied to the lower end'of the socket, the said screw being. provided with a handle, 16 for convenience in turning the same in effecting adjustment. Adjacent each turn-table an upright guide-bar 17, Fig. 11 is located, around which the paper leaving the roll supported by such turntable changes its direction. I

17 is a guide for the upper edge of the paper, such guide being fitted upon the upright guide-bar 17 and adjusted up and down by means of an adjusting screw which is furnished with an operating handle 17*, Figs. 11 and 12.

At 18, 18, are triangular doubling-folders, one at each side of the machine, by means of which each of the webs or strips of paper is doubled upon itself longitudinally as it travels from the supply-roll toward the 'bodyof the machine. 7 7

18 Figs. 11 and 12 is a cloth-covered presser-bar 1n conjunction with each doubling-folder, the corresponding web or strip of paper passing between the said presser-bar and the flat surface of the folder and being held by the presser-bar close to the said surface.

At 19, 19, Figs. 12, 13,and 15 are two press-bars extending longitudinally across the machine, one above the other, and at 20, 20, are a pair of feed-rolls adjacent said horizontal press-bars. From the apex of the triangular folder, the doubled web or strip of paper passes between the two pressbars, and then between the two feed-rolls. The upper press-bar and upper feed-roll are supported by arms 23, 23, shown best in Figs. 15 and 16, mounted loosely upon a transversely extending shaft 24 which is provided in bearings on the opposite sideframes of the machine. The lower press bar and lower feed-roll are supported by arms 23 23, that also are mounted loosely upon the said shaft 24. At each side of the machine, a downwardly-extending portion of the arm-23 is connected with a similar portion of the arm 23 by toggle-links 23", 23*, the meeting ends of which are pivoted to a cross-rod 23 carried by the arms 23 28 of a rocker, the latter having its rockshaft 23 journaled in the opposite sideframes of the machine and provided with a third arm, 23, serving as a handle by means of which the frames may be moved manually to separate the feed-rolls and pressbars to permit of the threading-in of the web or strip of paper, and afterward may be moved toward each other to cause the feed-rolls and press-bars to approach and compress the web between them. 7

The purpose in using the press-bars is to obviate the difficulty which is experienced in practice in causing the peak or pointof the folder to enter properly into the nip of apair of cylindrical rolls. From between the feed-rolls 20, 20, the web or strip of paper passes over the shaft 2 1 on which the arms 23, 23 are hung, and between a second pair of feed-rolls, 25, 25. These last are covered with frictional surfacing material which is indicated in Figs. 16 and 18. The shafts of feed-rolls 25, 25, are journaled in bearings with which the opposite sideframes of the machine are provided. At the delivery side of these feed-rolls, a fixed shear-blade 26, Figs. 13 and 18 islocated. The web or strip passes between the said fixed shear-blade and a movable shear-blade 27 carried by a cross-bar 27*, Figs. 11, 12, 15, 16 and 18 which is movable vertically in guides 27*, 27', on the opposite sideframes of the machine. The said cross-bar is connected operatively with the main shaft, A, of the machine through the instrumentality of devices by means of which the cross-bar and shear-blade carried thereby are raised andlowered at the proper times in the working of the machine. In the present instance, the said devices consist of a cam 27, Fig. 18, mounted on shaft A, levers 27 in engagement with the said cam, one of such levers being shown in Fig. 18, and a link 27 connecting the outer arm of said lever with one end of the cross-bar. The lower feed-roll 20 is driven by gearconnections from the shaft A, the said shaft having for the purpose a large bevel gear 28 thereon, Figs. 12 and 13 meshing with asmall bevel gear 28 on the inner end of a short cross-shaft 28", Fig. 12, carrying at its outer end a change spur-gear 29 meshing with a spur-gear 30 fast with a sprocket-wheel 31, around which and a sprocket wheel 32 on one end of the shaft 24 passes a sprocket chain 32*. Shaft 24 is provided at its opposite end with a spur pinion 2 1, see more particularly Figs. 12 and 16 meshing with a spur gear 24* fast upon the lower feed-roll 20. Thereby the said lower feed-roll, is driven. The upper feed-roll 20 is driven from the lower one by spur-pinions 20 Fig. 12. The feed-rolls 25, 25, are driven by means of spur pinion 2 1 which latter engages a spur-gear 25 Figs. 12 and 16 that is mounted upon the shaft of the lower roll 25 with capacity to turn thereon, the said gear being connected with the said shaft by an adjustable frictional coupling arrangement, of well-known character, by

means of which the shaft is caused normally to turn. in unison with the gear. For

the purpose of arresting the rotation of the second pair of feed-rolls as the shearblades close together, a pin 27", Figs. 11,

15 and 16 is provided upon one end of the cross-bar 27 carrying the movable blade 27,

this pin working in a slot in an arm 27 which is attached to a right-and-left screw 27 that is fitted to correspondingly-thread ed holes in arms 27 27 located at opposite sides of the collar 27 fixed on the shaft of the lower feed-roll 25. One of the said arms is bolted to the machine-framing and the other thereof is supported by the first. When, now, the arm 27 is swung by the rising and falling movements of the crossbar 27 so as to turn the right-and-left screw first in one direction and then in the other, the arms 27 27 are moved toward and from each other so as alternately to clamp the collar between them, and thereby hold the lower feed-roll 25 from turning, and to release the said feed-roll so as to permit it to turn. While the arms are holding the collar 27* so as to prevent the lower feedroll 25 from turning, the friction-coupling aforesaid slips relative to the spur-gear 25*.

For the purpose of varying the feed for different lengths of fly-leaves or end-papers, the gears 29, 30 are replaced by others having different numbers of teeth. The general arrangement comprising the tables 3, the lower way for the fly-leaves or endpapers,the upper way for the signatures, the feed-chains. the means for actuating the feed-chains. the jog or registering devices 6 and 8, in the case of the machine shown in F gs. 11,12. 13,etc., resembles in the main that of the machine first described. The lower sets of strips 32, 32, are omitted, however, although they may be em loyed if desired.

Intermediate the shear-blades or cutters 26, 27, and the receiving ends of the feedchains. are located two sets of guides or c nducting devices 36, see more particularly Figs. 13 and 18, into which the folded webs or strips of paper are advanced by the action of the second pair of feed-rolls. These guides or conductors comprise upper and lower bars arranged in pairs and mounted fixedly on a rocker 36, Fig. 18, which is journaled on the machine framing as indicated in Fig. 19. A depending bar 36 Figs. 13 and 18 is jointed to the rocker and is furnished with a roll which rests upon the periphery of a cam 36 on shaft A. The said cam acts to raise the rocker and its guides or conductors, and the parts descend again under the action of gravity. By means of the cam the rocker and its guides are raised during the advanceof the paper that is occasioned by the intermittent rotation of the second pair of feed-rolls 25, 25, so as to enable the leading end of the paper to pass above and clear the projections of the feed-chains. The timing of the feedchains is such that duringa part of the advance of the paper, certain of the projections thereon are in the path of the leading end of the paper, the feed-chains being in motion for a part of the time, and standing still for a part of the time. Hence, in order that the paper may not be obstructed in such part of its advance the guides or conducting devices are raised so as to elevate the leading end of the paper above the said projections. Upon the carrying shaft 41 for the sprocket-wheels at the receiving ends of the feed-chains are mounted feedingdisks 37 Figs. 11 and 19, having frictional peripheries, and upon the rocker are loosely hung arms 37 carrying presser-disks or rolls 37*, the said arms being drawn down by springs 37 to cause the said presserdisks to coact with the feeding-disks aforesaid by compressing the paper against the latter. One end of a spring 37 (see Figs. 19 and 19 is connected with a small bracket 37 on the arm 37 carrying one of the said presser-disks, the other end thereof being connected with an adjacent upper guide 36. The hubs 37 of the presser-disks, or the studs upon which the said disks are mounted, project above certain of the guides of the rocker as shown in Figs. 19 and 19 so that in the lifting movement of the rocker the said guides lift the presser-disks and thereby separate them from the feeding-disks the parts are shown thus separated in Fig. 19. When the rocker is permitted to descend, however, the presserdisks are lowered so as to press the paper against the feeding-disks. Thereby the paper is gripped between the presser and feeding-disks and the feed-rolls so that in consequence the fly-leaf or end-paper, which by this time has been severed from the continuous web or strip by the closing of the shears or cutters, is fed forward by means of the presser and feeding-disks, it being thereby caused to travel upon the leading end of the guideway for fly-leaves or endpapers at the same rate of speed as the feedchains are being advanced at the time, and in advance of a set of the projections of the feed-chains. In this manner the severed fly-leaf or end-paper is fed from the shears or cutters to the leading end of the said guideway and is delivered to and presented upon the latter in position to be engaged by the said set of projections preparatory to being carried forward thereby through the machine. The upper bars of the guides or conductors 36 are extended somewhat in the direction of the length of the guideway, as shown best in Figs. 13, 19 and 19 to. hold the paper down upon the guideway, and, in addition, for the purpose of applying a sort of drag. to the upper surface of the paper, flexible strips 38*, Figs. 11, 19 and 19 are attached to a short bar 38 extending crosswise above the guideway, the said strips hanging down upon the guideway so as to rest upon the paper as it passes along the latter.

The signatures are placed upon an upper shelf 39 extending crosswise of the machine and supported by stands rising from the main bed or table of the machine. From the said table rise inner and outer sideend of the rod 4 pieces 39*, 39, and'a front piece 59 as well as swinging rear pieces 39, 39. See more particularly Fig. 12. The hopper construction has the customary adjustments to enable thesame to be accommodated to the size of signatures to be operated upon.

A rocking frame 40,Fig.,13 mounted upon. the upper shelf 39, and having its axis in line withthe upper front corner of the said shelf has connected therewith a Thar 4O provided with a roll engaged by a grooved cam 40 onthe shaft A, the said rocker having arms in which is mounted a pipe 40 Figs. 11 and 14 having at the opfpositeextrernities thereof the suction-pickers 40. The said pipe 40 is connected by means of flexible tubing 40 with pump cylinders 40 that are hung upon a central post 4 a cross-head that is attached to the upper in a groove of a cam 40 on the line shaft. A second rocker 15, Fig. 13, also having its axis in line with the front upper corner of the upper bed 39, has laterally-extending guide-arms 45, 45*, Fig. 14 on which are I mounted blocks 45, 45, carrying the sepathe separators.

rators 45, 45 which last are shown best in Figs. 14 and 14. Fig. 14 shows opposite elevations and a plan View of one of The said separators are similar in. type and mode of operation to those of U. S. Letters Patent to Stuart H.

Pray, No. 767,081, Aug. 9,1904. The said blocks 45, 45, are capable of sliding upon the said. guide-arms in the direction of the length of the latter and transversely with reference to the machine. The movement of the said blocks toward the middle of the machine is limited by means of stops 45 which are bolted to the said guide-bars. By, means of connecting-rods 45 45 the;

blocks 45, 45, are joined operatively with the upwardly-extending ar'msof bell-cranksf 45 45 that are mounted pivotally upon the intermediate portion of the said second rocker 45,-

The horizontal arm. of one of the"-bell-- cranks carries a pin 45 working in the slot that is formed in the corresponding arm of the other bell-crank, and this pin is joined yoke 45. provided with a roll 'working in agroove of the upper shelf 39 are fixed blocks 46, 46,

with which engage anti-friction rolls 46,"

Upon In the depressed the second rocker the separator-1 the axis' of' the shaft. Upon the rock-shaft the guide portions of the said rockers, the anti-friction rolls on the said blocks take against the horizontal under surfaces of the fixed blocks.- The grooved cam 45, acting to raise the yoke andconnectingbar,

' transmits force to the horizontal arms of the tions until the said rolls clear the said horizontal faces-of the fixed blocks, at which timethe separator-carrying blocks will have become engaged with the fixed stops onthe guide-bars. The inward movement of the separator-carrying blocks having been arrested byreason of the engagement of the saidblocks with the said fixed stops on the guide-bars, the bell-cranks "are prevented further with relation to the second rocker, and the continued transmissionof upwardly-acting force through. the

yoke andconnecting bar aforesaid acts now to raise-the second rocker and the separators which are applied'thereto.

For the purpose of transferring the bot: tom signature from'the stack or.'pile to the upper surface ofthe guideway for signatures, a pair of'nippers is provided at each side ofv the machine. 'The two pairs of nippers are mounted upon the opposite ends of 'a'rock '-shaft 47 Figs.
